Ancient Martian Life Clues Could Hide in Giant Water-Carved Caves
Introduction: A Hidden Biosignature Archive on Mars Scientists are increasingly eyeing Mars’ subsurface and its cave networks as prime repositories for evidence of ancient life. Recent discussions point to colossal karstic caves—systems formed when slightly acidic water dissolved bedrock—as ideal environments where biosignatures could be preserved for billions of years. If confirmed, these caves could…
